Care Navigation and Coordination Program on Reducing Hospital Use for Adults with Complex Health and Psychosocial Needs in South West Sydney, Australia.

PCBH is associated with a notable reduction in unplanned hospitalisations and total bed days. However, reduction in ED presentations is similar between the intervention and comparison cohorts. Future initiatives should focus on a shared vision of integrated care, robust leadership, and participative co-creation with service-level stakeholders. Sustained program establishment, a multidisciplinary care coordinator team, and an early creation of robust evaluation strategy must be considered.
